Erik Schonfeld writes about the information overload challenge, showing the overblown, Tweet-filled desktop of Seesmic founder Loic Le Meur.
While Twitter presents new challenges staying dialed in to the stream, it still does a helluva job vetting news and information once you get your network in place. It's that last part {discovery} that poses the biggest challenge. Why else would you have to create 20 columns to scrape enough information together to get a few key morsels?
I think that's why you're seeing Twitter and other ecosystem partners focusing on search and curation. Once that starts to improve, I think you'll see higher value networks start to bloom -- and in much shorter time frames. We can then leave the "20-column" configurations in the rear-view mirror.

"It’s 18 months later and the problem hasn’t been solved. The screenshot I took back then still resonates because the noise is worse than ever. Indeed, it is being magnified every day as more people pile onto Twitter and Facebook and new apps yet to crest like Google Wave. The data stream is growing stronger, but so too is the danger of drowning in all that information."
